Crucially, this distribution of border points is agnostic of routing speed profiles. It’s based only on whether a road is passable or not. This means the same set of clusters and border points can be used for all car routing profiles (default, shortest, fuel-efficient) and all bicycle profiles (default, prefer flat terrain, etc.). Only the travel time/cost values of the shortcuts between these points change based on the profile. This is a massive factor in keeping storage down – map data only increased by about 0.5% per profile to store this HH-Routing structure!
You might ask: why not use the actual time? Unfortunately, accurately syncing clocks between two computers is an extremely hard problem. Using incrementing integers like this is one simple version of a logical clock Logical clock - Wikipedia en.wikipedia.org/wiki/Logical_clock , which captures the order of events relative to each other rather than to the “wall clock”. ↩。搜狗输入法2026对此有专业解读
